Throughout the history of the Church the teaching of the Immaculate Conception grew in ecclesiastical and popular status. The Catechism of the Church has adopted the importance of the Feast;
490: To become the mother of the Savior, Mary "was enriched by God with gifts appropriate to such a role." The angel Gabriel at the moment of the annunciation salutes her as "full of grace". In fact, in order for Mary to be able to give the free assent of her faith to the announcement of her vocation, it was necessary that she be wholly borne by God's grace.
491: Through the centuries the Church has become ever more aware that Mary, "full of grace" through God, was redeemed from the moment of her conception. That is what the dogma of the Immaculate Conception confesses, as Pope Pius IX proclaimed in 1854:
The most Blessed Virgin Mary was, from the first moment of her conception, by a singular grace and privilege of almighty God and by virtue of the merits of Jesus Christ, Savior of the human race, preserved immune from all stain of original sin.
492: The "splendor of an entirely unique holiness" by which Mary is "enriched from the first instant of her conception" comes wholly from Christ: she is "redeemed, in a more exalted fashion, by reason of the merits of her Son". The Father blessed Mary more than any other created person "in Christ with every spiritual blessing in the heavenly places" and chose her "in Christ before the foundation of the world, to be holy and blameless before him in love".
493: The Fathers of the Eastern tradition call the Mother of God "the All-Holy" (Panagia), and celebrate her as "free from any stain of sin, as though fashioned by the Holy Spirit and formed as a new creature". By the grace of God Mary remained free of every personal sin her whole life long.
Last year Pope Francis taught, in St. Peter’s Square; The Pope said on Dec. 8 that the Blessed Virgin Mary's encounter with the Angel Gabriel, described in St. Luke's Gospel, revealed her deep humility. “Within the domestic walls, a person reveals him or herself better than elsewhere. And it is precisely within that domestic intimacy that the Gospel gives us a detail that reveals the beauty of Mary's heart,' he said. 'The angel calls her 'full of grace.' If she is full of grace, it means the Madonna is void of evil: she is without sin, Immaculate.'
Pope Francis has offered a singular prayer for the Immaculate Conception;
O Mary, our Immaculate Mother,
On your feast day I come to you,
And I come not alone:
I bring with me all those with whom your Son entrusted to me,
In this city of Rome and in the entire world,
That you may bless them and preserve them from harm.
I bring to you, Mother, children,
Especially those who are alone, abandoned,
And for this reason are tricked and exploited.
I bring to you, Mother, families,
Who carry forward life and society
With their daily and hidden efforts;
In a special way the families who struggle the most
For their many internal and external problems.
I bring to you, Mother, all workers, both men and women,
And I entrust to you especially those who, out of need,
Are forced to work in an unworthy profession
And those who have lost work or are unable to find it.
We are in need of your immaculate gaze,
To rediscover the ability to look upon persons and things
With respect and awareness,
Without egotistical or hypocritical interests.
We are in need of your immaculate heart,
To love freely,
Without secondary aims but seeking the good of the other,
With simplicity and sincerity, renouncing masks and tricks.
We are in need of your immaculate hands,
To caress with tenderness,
To touch the flesh of Jesus
In our poor, sick, or despised brethren,
To raise up those who have fallen and support those who waver.
We are in need of your immaculate feet,
To go toward those who know not how to make the first step,
To walk on the paths of those who are lost,
To find those who feel alone.
We thank you, O Mother, because in showing yourself to us
You free us of all stain of sin;
You remind us that what comes first is the grace of God,
The love of Jesus Christ who gave his life for us,
The strength of the Holy Spirit which renews all things.
Let us not give in to discouragement,
But, trusting in your constant help,
Let us engage ourselves fully in renewal of self,
Of this city and of the entire world.
Pray for us, Holy Mother of God!
The Immaculate state of Mary is not something to which we could aspire, but praise and for which we give thanks as without the Immaculate Conception the Cross would have been meaningless for our salvation.
